Soybean cultivar sg1330nrr

ABSTRACT

A novel soybean cultivar, designated SG133ONRR, is disclosed. The invention relates to the seeds of soybean cultivar SG1330NRR, to the plants of soybean SG1330NRR and to methods for producing a soybean plant produced by crossing the cultivar SG1330NRR with itself or another soybean variety. The invention further relates to hybrid soybean seeds and plants produced by crossing the cultivar SG1330NRR with another soybean cultivar.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinctive soybean cultivar,designated SG1330NRR. There are numerous steps in the development of anynovel, desirable plant germplasm. Plant breeding begins with theanalysis and definition of problems and weaknesses of the currentgermplasm, the establishment of program goals, and the definition ofspecific breeding objectives. The next step is selection of germplasmthat possess the traits to meet the program goals. The goal is tocombine in a single variety an improved combination of desirable traitsfrom the parental germplasm. These important traits may include higherseed yield, resistance to diseases and insects, better stems and roots,tolerance to drought and heat, and better agronomic quality.

Choice of breeding or selection methods depends on the mode of plantreproduction, the heritability of the trait(s) being improved, and thetype of cultivar used commercially (e.g., F₁ hybrid cultivar, purelinecultivar, etc.). For highly heritable traits, a choice of superiorindividual plants evaluated at a single location will be effective,whereas for traits with low heritability, selection should be based onmean values obtained from replicated evaluations of families of relatedplants. Popular selection methods commonly include pedigree selection,modified pedigree selection, mass selection, and recurrent selection.

The complexity of inheritance influences choice of the breeding method.Backcross breeding is used to transfer one or a few favorable genes fora highly heritable trait into a desirable cultivar. This approach hasbeen used extensively for breeding disease-resistant cultivars. Variousrecurrent selection techniques are used to improve quantitativelyinherited traits controlled by numerous genes. The use of recurrentselection in self-pollinating crops depends on the ease of pollination,the frequency of successful hybrids from each pollination, and thenumber of hybrid offspring from each successful cross.

Each breeding program should include a periodic, objective evaluation ofthe efficiency of the breeding procedure. Evaluation criteria varydepending on the goal and objectives, but should include gain fromselection per year based on comparisons to an appropriate standard,overall value of the advanced breeding lines, and number of successfulcultivars produced per unit of input (e.g., per year, per dollarexpended, etc.).

Promising advanced breeding lines are thoroughly tested and compared toappropriate standards in environments representative of the commercialtarget area(s) for three or more years. The best lines are candidatesfor new commercial cultivars; those still deficient in a few traits maybe used as parents to produce new populations for further selection.

These processes, which lead to the final step of marketing anddistribution, usually take from eight to 12 years from the time thefirst cross is made. Therefore, development of new cultivars is atime-consuming process that requires precise forward planning, efficientuse of resources, and a minimum of changes in direction.

A most difficult task is the identification of individuals that aregenetically superior, because for most traits the true genotypic valueis masked by other confounding plant traits or environmental factors.One method of identifying a superior plant is to observe its performancerelative to other experimental plants and to a widely grown standardcultivar. If a single observation is inconclusive, replicatedobservations provide a better estimate of its genetic worth.

The goal of plant breeding is to develop new, unique and superiorsoybean cultivars and hybrids. The breeder initially selects and crossestwo or more parental lines, followed by repeated selfing and selection,producing many new genetic combinations. The breeder can theoreticallygenerate billions of different genetic combinations via crossing,selfing and mutations. The breeder has no direct control at the cellularlevel. Therefore, two breeders will never develop the same line, or evenvery similar lines, having the same soybean traits.

Each year, the plant breeder selects the germplasm to advance to thenext generation. This germplasm is grown under unique and differentgeographical, climatic and soil conditions, and further selections arethen made, during and at the end of the growing season. The cultivarswhich are developed are unpredictable. This unpredict-ability is becausethe breeder's selection occurs in unique environments, with no controlat the DNA level (using conventional breeding procedures), and withmillions of different possible genetic combinations being generated. Abreeder of ordinary skill in the art cannot predict the final resultinglines he develops, except possibly in a very gross and general fashion.The same breeder cannot produce the same cultivar twice by using theexact same original parents and the same selection techniques. Thisunpredictability results in the expenditure of large amounts of researchmonies to develop superior new soybean cultivars.

The development of new soybean cultivars requires the development andselection of soybean varieties, the crossing of these varieties andselection of superior hybrid crosses. The hybrid seed is produced bymanual crosses between selected male-fertile parents or by using malesterility systems. These hybrids are selected for certain single genetraits such as pod color, flower color, pubescence color or herbicideresistance which indicate that the seed is truly a hybrid. Additionaldata on parental lines, as well as the phenotype of the hybrid,influence the breeder's decision whether to continue with the specifichybrid cross.

Pedigree breeding and recurrent selection breeding methods are used todevelop cultivars from breeding populations. Breeding programs combinedesirable traits from two or more cultivars or various broad-basedsources into breeding pools from which cultivars are developed byselfing and selection of desired phenotypes. The new cultivars areevaluated to determine which have commercial potential.

Pedigree breeding is used commonly for the improvement ofself-pollinating crops. Two parents which possess favorable,complementary traits are crossed to produce an F₁. An F₂ population isproduced by selfing one or several F₁'s. Selection of the bestindividuals may begin in the F₂ population; then, beginning in the F₃,the best individuals in the best families are selected. Replicatedtesting of families can begin in the F₄ generation to improve theeffectiveness of selection for traits with low heritability. At anadvanced stage of inbreeding (i.e., F₆ and F₇), the best lines ormixtures of phenotypically similar lines are tested for potentialrelease as new cultivars.

Mass and recurrent selections can be used to improve populations ofeither self- or cross-pollinating crops. A genetically variablepopulation of heterozygous individuals is either identified or createdby intercrossing several different parents. The best plants are selectedbased on individual superiority, outstanding progeny, or excellentcombining ability. The selected plants are intercrossed to produce a newpopulation in which further cycles of selection are continued.

Backcross breeding has been used to transfer genes for a simplyinherited, highly heritable trait into a desirable homozygous cultivaror inbred line which is the recurrent parent. The source of the trait tobe transferred is called the donor parent. The resulting plant isexpected to have the attributes of,the recurrent parent (e.g., cultivar)and the desirable trait transferred from the donor parent. After theinitial cross, individuals possessing the phenotype of the donor parentare selected and repeatedly crossed (backcrossed) to the recurrentparent. The resulting plant is expected to have the attributes of therecurrent parent (e.g., cultivar) and the desirable trait transferredfrom the donor parent.

The single-seed descent procedure in the strict sense refers to plantinga segregating population, harvesting a sample of one seed per plant, andusing the one-seed sample to plant the next generation. When thepopulation has been advanced from the F₂ to the desired level ofinbreeding, the plants from which lines are derived will each trace todifferent F₂ individuals. The number of plants in a population declineseach generation due to failure of some seeds to germinate or some plantsto produce at least one seed. As a result, not all of the F₂ plantsoriginally sampled in the population will be represented by a progenywhen generation advance is completed.

In a multiple-seed procedure, soybean breeders commonly harvest one ormore pods from each plant in a population and thresh them together toform a bulk. Part of the bulk is used to plant the next generation andpart is put in reserve. The procedure has been referred to as modifiedsingle-seed descent or the pod-bulk technique.

The multiple-seed procedure has been used to save labor at harvest. Itis considerably faster to thresh pods with a machine than to remove oneseed from each by hand for the single-seed procedure. The multiple-seedprocedure also makes it possible to plant the same number of seeds of apopulation each generation of inbreeding. Enough seeds are harvested tomake up for those plants that did not germinate or produce seed.

Descriptions of other breeding methods that are commonly used fordifferent traits and crops can be found in one of several referencebooks (e.g., Allard, 1960; Simmonds, 1979; Sneep et al., 1979; Fehr,1987).

Proper testing should detect any major faults and establish the level ofsuperiority or improvement over current cultivars. In addition toshowing superior performance, there must be a demand for a new cultivarthat is compatible with industry standards or which creates a newmarket. The introduction of a new cultivar will incur additional coststo the seed producer, the grower, processor and consumer; for specialadvertising and marketing, altered seed and commercial productionpractices, and new product utilization. The testing preceding release ofa new cultivar should take into consideration research and developmentcosts as well as technical superiority of the final cultivar. Forseed-propagated cultivars, it must be feasible to produce seed easilyand economically.

Soybean, Glycine max (L), is an important and valuable field crop. Thus,a continuing goal of plant breeders is to develop stable, high yieldingsoybean cultivars that are agronomically sound. The reasons for thisgoal are obviously to maximize the amount of grain produced on the landused and to supply food for both animals and humans. To accomplish thisgoal, the soybean breeder must select and develop soybean plants thathave the traits that result in superior cultivars.

More preferably expression vectors are introduced into planttissues using the microprojectile media delivery with the biolisticdevice Agrobacterium-medicated transformation. Transformant plantsobtained with the protoplasm of the invention are intended to be withinthe scope of this invention.

FURTHER EMBODIMENTS OF THE INVENTION

With the advent of molecular biological techniques that have allowed theisolation and characterization of genes that encode specific proteinproducts, scientists in the field of plant biology developed a stronginterest in engineering the genome of plants to contain and expressforeign genes, or additional, or modified versions of native, orendogenous, genes (perhaps driven by different promoters) in order toalter the traits of a plant in a specific manner. Such foreignadditional and/or modified genes are referred to herein collectively as“transgenes”. Over the last fifteen to twenty years several methods forproducing transgenic plants have been developed, and the presentinvention, in particular embodiments, also relates to transformedversions of the claimed variety or line.

Plant transformation involves the construction of an expression vectorwhich will function in plant cells. Such a vector comprises DNAcomprising a gene under control of or operatively linked to a regulatoryelement (for example, a promoter). The expression vector may contain oneor more such operably linked gene/regulatory element combinations. Thevector(s) may be in the form of a plasmid, and can be used alone or incombination with other plasmids, to provide transformed soybean plants,using transformation methods as described below to incorporatetransgenes into the genetic material of the soybean plant(s).

Expression Vectors for Soybean Transformation: Marker Genes—Expressionvectors include at least one genetic marker, operably linked to aregulatory element (a promoter, for example) that allows transformedcells containing the marker to be either recovered by negativeselection, i.e., inhibiting growth of cells that do not contain theselectable marker gene, or by positive selection, i.e., screening forthe product encoded by the genetic marker. Many commonly used selectablemarker genes for plant transformation are well known in thetransformation arts, and include, for example, genes that code forenzymes that metabolically detoxify a selective chemical agent which maybe an antibiotic or a herbicide, or genes that encode an altered targetwhich is insensitive to the inhibitor. A few positive selection methodsare also known in the art.

One commonly used selectable marker gene for plant transformation is theneomycin phosphotransferase II (nptII) under the control of plantregulatory signals confers resistance to kanamycin. Fraley et al., Proc.Natl. Acad. Sci. U.S.A., 80:4803 (1983). Another commonly usedselectable marker gene is the hygromycin phosphotransferase gene whichconfers resistance to the antibiotic hygromycin. Vanden Elzen et al.,Plant Mol. Biol., 5:299 (1985).

Additional selectable marker genes of bacterial origin that conferresistance to antibiotics include gentamycin acetyl transferase,streptomycin phosphotransferase, aminoglycoside-3′-adenyl transferase,the bleomycin resistance determinant. Hayford et al., Plant Physiol.86:1216 (1988), Jones et al., Mol. Gen. Genet., 210:86 (1987), Svab etal., Plant Mol. Biol. 14:197 (1990<Hille et al., Plant Mol. Biol. 7:171(1986). Other selectable marker genes confer resistance to herbicidessuch as glyphosate, glufosinate or broxynil. Comai et al., Nature317:741-744 (1985), Gordon-Kamm et al., Plant Cell 2:603-618 (1990) andStalker et al., Science 242:419-423 (1988).

Other selectable marker genes for plant transformation are not ofbacterial origin. These genes include, for example, mouse dihydrofolatereductase, plant 5-enolpyruvylshikimate-3-phosphate synthase and plantacetolactate synthase. Eichholtz et al., Somatic CellMol. Genet. 13:67(1987), Shah et al., Science 233:478 (1986), Charest et al., Plant CellRep. 8:643 (1990).

Another class of marker genes for plant transformation require screeningof presumptively transformed plant cells rather than direct geneticselection of transformed cells for resistance to a toxic substance suchas an antibiotic. These genes are particularly useful to quantify orvisualize the spatial pattern of expression of a gene in specifictissues and are frequently referred to as reporter genes because theycan be fused to a gene or gene regulatory sequence for the investigationof gene expression. Commonly used genes for screening presumptivelytransformed cells include β-glucuronidase (GUS, β-galactosidase,luciferase and chloramphenicol, acetyltransferase. Jefferson, R. A.,Plant Mol. Biol. Rep. 5:387 (1987), Teeri et al., EMBO J. 8:343 (1989),Koncz et al., Proc. Natl. Acad. Sci U.S.A. 84:131 (1987), DeBlock etal., EMBO J. 3:1681 (1984).

Recently, in vivo methods for visualizing GUS activity that do notrequire destruction of plant tissue have been made available. MolecularProbes publication 2908, Imagene Green™, p. 1-4 (1993) and Naleway etal., J. Cell Biol. 115:151a (1991). However, these in vivo methods forvisualizing GUS activity have not proven useful for recovery oftransformed cells because of low sensitivity, high fluorescentbackgrounds and limitations associated with the use of luciferase genesas selectable markers.

More recently, a gene encoding Green Fluorescent Protein (GFP) has beenutilized as a marker for gene expression in prokaryotic and eukaryoticcells. Chalfie et al., Science 263:802 (1994). GFP and mutants of GFPmay be used as screenable markers.

Promoters—Genes included in expression vectors must be driven bynucleotide sequence comprising a regulatory element, for example, apromoter. Several types of promoters are now well known in thetransformation arts, as are other regulatory elements that can be usedalone or in combination with promoters.

As used herein, “promoter” includes reference to a region of DNAupstream from the start of transcription and involved in recognition andbinding of RNA polymerase and other proteins to initiate transcription.A “plant promoter” is a promoter capable of initiating transcription inplant cells. Examples of promoters under developmental control includepromoters that preferentially initiate transcription in certain tissues,such as leaves, roots, seeds, fibers, xylem vessels, tracheids, orsclerenchyma. Such promoters are referred to as “tissue-preferred”.Promoters which intitiate transcription only in certain tissue arereferred to as “tissue-specific”. A “cell type” specific promoterprimarily drives expression in certain cell types in one or more organs,for example, vascular cells in roots or leaves. An “inducible” promoteris a promoter which is under environmental control. Examples ofenvironmental conditions that may effect transcription by induciblepromoters include anaerobic conditions or the presence of light.Tissue-specific, tissue-preferred, cell type specific, and induciblepromoters constitute the class of “non-constitutive” promoters. A“constitutive” promoter is a promoter which is active under mostenvironmental conditions.

A. Inducible Promoters—An inducible promoter is operably linked to agene for expression in soybean. Optionally, the inducible promoter isoperably linked to a nucleotide sequence encoding a signal sequencewhich is operably linked to a gene for expression in soybean. With aninducible promoter the rate of transcription increases in response to aninducing agent.

Any inducible promoter can be used in the instant invention. See Ward etal., Plant Mol. Biol. 22:361-366 (1993). Exemplary inducible promotersinclude, but are not limited to, that from the ACEI system whichresponds to copper (Mett et al., PNAS 90:4567-4571 (1993)); In2 genefrom maize which responds to benzenesulfonamide herbicide safeners(Hershey et al., Mol. Gen Genetics 227:229-237 (1991) and Gatz et al.,Mol. Gen. Genetics 243:32-38 (1994)) or Tet repressor from Tn10 (Gatz etal., Mol. Gen. Genetics 227:229-237 (1991). A particularly preferredinducible promoter is a promoter that responds to an inducing agent towhich plants do not normally respond. An exemplary inducible promoter isthe inducible promoter from a steroid hormone gene, the transcriptionalactivity of which is induced by a glucocorticosteroid hormone. Schena etal., Proc. Natl. Acad. Sci. U.S.A. 88:0421 (1991).

B. Constitutive Promoters—A constitutive promoter is operably linked toa gene for expression in soybean or the constitutive promoter isoperably linked to a nucleotide sequence encoding a signal sequencewhich is operably linked to a gene for expression in soybean.

Many different constitutive promoters can be utilized in the instantinvention. Exemplary constitutive promoters include, but are not limitedto, the promoters from plant viruses such as the 35S promoter from CaMV(Odell et al., Nature 313:810-812 (1985) and the promoters from suchgenes as rice actin (McElroy et al., Plant Cell 2:163-171 (1990));ubiquitin (Christensen et al., Plant Mol. Biol. 12:619-632 (1989) andChristensen et al., Plant Mol. Biol. 18:675-689 (1992)); pEMU (Last etal., Theor. Appl. Genet. 81:581-588 (1991)); MAS (Velten et al., EMBO J.3:2723-2730 (1984)) and maize H3 histone (Lepetit et al., Mol. Gen.Genetics 231:276-285 (1992) and Atanassova et al., Plant Journal 2 (3):291-300 (1992)).

The ALS promoter, Xba1/Ncol fragment 5′ to the Brassica napus ALS3structural gene (or a nucleotide sequence similarity to said Xba1/Ncolfragment), represents a particularly useful constitutive promoter. SeePCT application WO96/30530.

C. Tissue-specific or Tissue-preferred Promoters—A tissue-specificpromoter is operably linked to a gene for expression in soybean.Optionally, the tissue-specific promoter is operably linked to anucleotide sequence encoding a signal sequence which is operably linkedto a gene for expression in soybean. Plants transformed with a gene ofinterest operably linked to a tissue-specific promoter produce theprotein product of the transgene exclusively, or preferentially, in aspecific tissue.

Any tissue-specific or tissue-preferred promoter can be utilized in theinstant invention. Exemplary tissue-specific or tissue-preferredpromoters include, but are not limited to, a root-preferredpromoter—such as that from the phaseolin gene (Murai et al., Science23:476-482 (1983) and Sengupta-Gopalan et al., Proc. Natl. Acad. Sci.U.S.A. 82:3320-3324 (1985)); a leaf-specific and light-induced promotersuch as that from cab or rubisco (Simpson et al., EMBO J.4(11):2723-2729 (1985) and Timko et al., Nature 318:579-582 (1985)); ananther-specific promoter such as that from LAT52 (Twell et al., Mol.Gen. Genetics 217:240-245 (1989)); a pollen-specific promoter such asthat from Zm13 (Guerrero et al., Mol. Gen. Genetics 244:161-168 (1993))or a microspore-preferred promoter such as that from apg (Twell et al.,Sex. Plant Reprod. 6:217-224 (1993). Signal Sequences for TargetingProteins to Subcellular Compartments

Transport of protein produced by transgenes to a subcellular compartmentsuch as the chloroplast, vacuole, peroxisome, glyoxysome, cell wall ormitochondroin or for secretion into the apoplast, is accomplished bymeans of operably linking the nucleotide sequence encoding a signalsequence to the 5′ and/or 3′ region of a gene encoding the protein ofinterest. Targeting sequences at the 5′ and/or 3′ end of the structuralgene may determine, during protein synthesis and processing, where theencoded protein is ultimately compartmentalized.

The presence of a signal sequence directs a polypeptide to either anintracellular organelle or subcellular compartment or for secretion tothe apoplast. Many signal sequences are known in the art.

Foreign Protein Genes and Agronomic Genes—With transgenic plantsaccording to the present invention, a foreign protein can be produced incommercial quantities. Thus, techniques for the selection andpropagation of transformed plants, which are well understood in the art,yield a plurality of transgenic plants which are harvested in aconventional manner, and a foreign protein then can be extracted from atissue of interest or from total biomass. Protein extraction from plantbiomass can be accomplished by known methods which are discussed, forexample, by Heney and Orr, Anal. Biochem. 114:92-6 (1981).

According to a preferred embodiment, the transgenic plant provided forcommercial production of foreign protein is a soybean plant. In anotherpreferred embodiment, the biomass of interest is seed. For therelatively small number of transgenic plants that show higher levels ofexpression, a genetic map can be generated, primarily via conventionalRFLP, PCR and SSR analysis, which identifies the approximate chromosomallocation of the integrated DNA molecule. For exemplary methodologies inthis regard, see Glick and Thompson, Methods in Plant Molecular Biologyand Biotechnology CRC Press, Boca Raton 269:284 (1993). Map informationconcerning chromosomal location is useful for proprietary protection ofa subject transgenic plant. If unauthorized propagation is undertakenand crosses made with other germplasm, the map of the integration regioncan be compared to similar maps for suspect plants, to determine if thelatter have a common parentage with the subject plant. Map comparisonswould involve hybridizations, RFLP, PCR, SSR and sequencing, all ofwhich are conventional techniques.

Likewise, by means of the present invention, agronomic genes can beexpressed in transformed plants. More particularly, plants can begenetically engineered to express various phenotypes of agronomicinterest. Exemplary genes implicated in this regard include, but are notlimited to, those categorized below:

-   -   1. Genes That Confer Resistance to Pests or Disease and That        Encode:    -   A. Plant disease resistance genes. Plant defenses are often        activated by specific interaction between the product of a        disease resistance gene (R) in the plant and the product of a        corresponding avirulence (Avr) gene in the pathogen. A plant        variety can be transformed with cloned resistance gene to        engineer plants that are resistant to specific pathogen strains.        See, for example Jones et al., Science 266:789 (1994) (cloning        of the tomato Cf-9 gene for resistance to Cladosporium fulvum);        Martin et al., Science 262:1432 (1993) (tomato P to gene for        resistance to Pseudomonas syringae pv. Tomato encoddes a protein        kinase); Mindrinos et al., Cell 78:1089 (1994) (Arabidopsis RSP2        gene for resistance to Pseudomonas syringae).    -   B. A gene conferring resistance to a pest, such as soybean cyst        nematode. See e.g., PCT Application WO96/30517; PCT Application        WO93/19181.    -   C. A Bacillus thuringiensis protein, a derivative thereof or a        synthetic polypeptide modeled thereon. See, for example, Geiser        et al., Gene 48:109 (1986), who disclose the cloning and        nucleotide sequence of a Bt δ-endotoxin gene. Moreover, DNA        molecules encoding δendotoxin genes can be purchased from        American Type Culture Collection, Manassas, Va., for example,        under ATCC Accession Nos. 40098, 67136, 31995 and 31998.    -   D. A lectin. See, for example, the disclose by Van Damme et al.,        Plant Molec. Biol. 24:25 (1994), who disclose the nucleotide        sequences of several Clivia miniata mannose-binding lectin        genes.    -   E. A vitamin-binding protein such as avidin. See PCT application        US93/06487, the contents of which are hereby incorporated by        reference. The application teaches the use of avidin and avidin        homologues as larvicides against insect pests.

F. An enzyme inhibitor, for example, a protease or proteinase inhibitoror an amylase inhibitor. See, for example, Abe et al., J. Biol. Chem.262:16793 (1987) (nucleotide sequence of rice cysteine proteinaseinhibitor), Huub et al., Plant Molec. Biol. 21:985 (1993) (nucleotidesequence of cDNA encoding tobacco proteinase inhibitor I), Sumitani etal., Biosci. Biotech. Biochem. 57:1243 (1993) (nucleotide sequence ofStreptomyces nitrosporeus α-amylase inhibitor) and U.S. Pat. No.5,494,813 (Hepher and Atkinson, issued Feb. 27, 1996).

-   -   G. An insect-specific hormone or pheromone such as an        ecdysteroid and juvenile hormone, a variant thereof, a mimetic        based thereon, or an antagonist or agonist thereof. See, for        example, the disclosure by Hammock et al., Nature 344:458        (1990), of baculovirus expression of cloned juvenile hormone        esterase, an inactivator of juvenile hormone.    -   H. An insect-specific peptide or neuropeptide which, upon        expression, disrupts the physiology of the affected pest. For        example, see the disclosures of Regan, J. Biol. Chem.        269:9 (1994) (expression cloning yields DNA coding for insect        diuretic hormone receptor), and Pratt et al., Biochem. Biophys.        Res. Comm. 163:1243 (1989) (an allostatin is identified in        Diploptera puntata). See also U.S. Pat. No.5,266,317 to Tomalski        et al., who disclose genes encoding insect-specific, paralytic        neurotoxins.    -   I. An insect-specific venom produced in nature by a snake, a        wasp, etc. For example, see Pang et al., Gene 116:165 (1992),        for disclosure of heterologous expression in plants of a gene        coding for a scorpion insectotoxic peptide.    -   J. An enzyme responsible for a hyperaccumulation of a        monterpene, a sesquiterpene, a steroid, hydroxamic acid, a        phenylpropanoid derivative or another non-protein molecule with        insecticidal activity.    -   K. An enzyme involved in the modification, including the        ost-translational modification, of a biologically active        molecule; for example, a glycolytic enzyme, a proteolytic        enzyme, a lipolytic enzyme, a nuclease, a cyclase, a        transaminase, an esterase, a hydrolase, a phosphatase, a kinase,        a phosphorylase, a polymerase, an elastase, a chitinase and a        glucanase, whether natural or synthetic. See PCT application WO        93/02197 in the name of Scott et al., which discloses the        nucleotide sequence of a callase gene. DNA molecules which        contain chitinase-encoding sequences can be obtained, for        example, from the ATCC under Accession Nos.39637 and 67152. See        also Kramer et al., Insect Biochem. Molec. Biol. 23:691 (1993),        who teach the nucleotide sequence of a cDNA encoding tobacco        hookworm chitinase, and Kawalleck et al., Plant Molec. Biol.        21:673 (1993), who provide the nucleotide sequence of the        parsley ubi4-2 polyubiquitin gene.    -   L. A molecule that stimulates signal transduction. For example,        see the disclosure by Botella et al., Plant Molec. Biol. 24:757        (1994), of nucleotide sequences for mung bean calmodulin cDNA        clones, and Griess et al., Plant Physiol. 104:1467 (1994), who        provide the nucleotide sequence of a maize calmodulin cDNA        clone.    -   M. A hydrophobic moment peptide. See PCT application WO95/16776        (disclosure of peptide derivatives of Tachyplesin which inhibit        fungal plant pathogens) and PCT application W095/18855 (teaches        synthetic antimicrobial peptides that confer disease        resistance), the respective contents of which are hereby        incorporated by reference.    -   N. A membrane permease, a channel former or a channel blocker.        For example, see the disclosure of Jaynes et al., Plant Sci        89:43 (1993), of heterologous expression of a cecropin-β, lytic        peptide analog to render transgenic tobacco plants resistant to        Pseudomonas solanacearum.    -   O. A viral-invasive protein or a complex toxin derived        therefrom. For example, the accumulation of viral coat proteins        in transformed plant cells imparts resistance to viral infection        and/or disease development effected by the virus from which the        coat protein gene is derived, as well as by related viruses. See        Beachy et al., Ann. rev. Phytopathol. 28:451 (1990). Coat        protein-mediated resistance has been conferred upon transformed        plants against alfalfa mosaic virus, cucumber mosaidc virus,        tobacco streak virus, potato virus X, potato virus Y, tobacco        etch virus, tobacco rattle virus and tobacco mosaic virus. Id.    -   P. An insect-specific antibody or an immunotoxin derived        therefrom. Thus, an antibody targeted to a critical metabolic        function in the insect gut would inactivate an affected enzyme,        killing the insect. Cf. Taylor et al., Abstract #497, Seventh        Int'l Symposium on Molecular Plant-Microbe Interactions        (Edinburgh, Scotland) (1994) (enzymatic inactivation in        transgenic tobacco via production of single-chain antibody        fragments).    -   Q. A virus-specific antibody. See, for example, Tavladoraki et        al., Nature 366:469 (1993), who show that transgenic plants        expressing recombinant antibody genes are protected from virus        attack.    -   R. A developmental-arrestive protein produced in nature by a        pathogen or a parasite. Thus, fungal endo α-1,        4-D-polygalacturonases facilitate fungal colonization and plant        nutrient release by solubilizing plant cell wall        homo-α-1,4-D-galacturonase. See Lamb et al., Bio/Technology        10:1436 (1992). The cloning and characterization of a gene which        encodes a bean endopolygalacturonase-inhibiting protein is        described by Toubart et al., Plant J. 2:367 (1992).    -   S. A development-arrestive protein produced in nature by a        plant. For example, Logemann et al., Bio/Technology 10:305        (1992), have shown that transgenic plants expressing the barley        ribosome-inactivting gene have an increased resistance to fungal        disease.    -   2. Genes That Confer Resistance to a Herbicide, For Example:    -   A. A herbicide that inhibits the growing point or meristem, such        as an imidazalinone or a sulfonylurea. Exemplary genes in this        category code for mutant ALS and AHAS enzyme as described, for        example, by Lee et al., EMBO J. 7:1241 (1988), and Miki et al.,        Theor. Appl. Genet. 80:449 (1990), respectively.    -   B. Glyphosate (resistance impaired by mutant        5-enolpyruvl-3-phosphikimate synthase (EPSP) and aroA genes,        respectively) and other phosphono compounds such as glufosinate        (phosphinothricin acetyl transferase, PAT and Streptomyces        hygroscopicus phosphinothricin-acetyl transferase, bar, genes),        and pyridinoxy or phenoxy proprionic acids and cycloshexones        (ACCase inhibitor-encoding genes). See, for example, U.S. Pat.        No. 4,940,835 to Shah, et al., which discloses the nucleotide        sequence of a form of EPSP which can confer glyphosate        resistance. A DNA molecule encoding a mutant aroA gene can be        obtained under ATCC accession number 39256, and the nucleotide        sequence of the mutant gene is disclosed in U.S. Pat. No.        4,769,061 to Comai. European patent application No. 0 333 033 to        Kumada et al., and U.S. Pat. No. 4,975,374 to Goodman et al.,        disclose nucleotide sequences of glutamine synthetase genes        which confer resistance to herbicides such as        L-phosphinothricin. The nucleotide sequence of a        phosphinothricin-acetyl-transferase gene is provided in European        application No.0 242 246 to Leemans et al., DeGreef et al.,        Bio/Technology 7:61 (1989), describe the production of        transgenic plants that express chimeric bar genes coding for        phosphinothricin acetyl transferase activity. Exemplary of genes        conferring resistance to phenoxy proprionic acids and        cycloshexones, such as sethoxydim and haloxyfop are the Acc1-S1,        Acc1-S2 and Acc1-S3 genes described by Marshall et al., Theor.        Appl. Genet. 83:435 (1992).    -   C. A herbicide that inhibits photosynthesis, such as a triazine        (psbA and gs+genes) and a benzonitrile (nitrilase gene).        Przibila et al., Plant Cell 3:169 (1991), describe the        transformation of Chlamydomonas with plasmids encoding mutant        psbA genes. Nucleotide sequences for nitrilase genes are        disclosed in U.S. Pat. No. 4,810,648 to Stalker, and DNA        molecules containing these genes are available under ATCC        Accession Nos. 53435, 67441, and 67442. Cloning and expression        of DNA coding for a glutathione S-transferase is described by        Hayes et al., Biochem. J. 285:173 (1992).    -   3. Genes That Confer or Contribute to a Value-Added Trait, Such        as:    -   A. Modified fatty acid metabolism, for example, by transforming        a plant with an antisense gene of stearoyl-ACP desaturase to        increase stearic acid content of the plant. See Knultzon et al.,        Proc. Natl. Acad. Sci. U.S.A. 89:2624 (1992).    -   B. Decreased phytate content—1) Introduction of a        phytase-encoding gene would enhance breakdown of phytate, adding        more free phosphate to the transformed plant. For example, see        Van Hartingsveldt et al., Gene 127:87 (1993), for a disclosure        of the nucleotide sequence of an Aspergillus niger phytase        gene. 2) A gene could be introduced that reduced phytate        content. In maize, this, for example, could be accomplished, by        cloning and then reintroducing DNA associated with the single        allele which is responsible for maize mutants characterized by        low levels of phytic acid. See Raboy et al., Maydica 35:383        (1990).    -   C. Modified carbohydrate composition effected, for example, by        transforming plants with a gene coding for an enzyme that alters        the branching pattern of starch. See Shiroza et al., J. Bacteol.        170:810 (1988) (nucleotide sequence of Streptococcus mutants        fructosyltransferase gene), Steinmetz et al., Mol. Gen. Genet.        20:220 (1985) (nucleotide sequence of Bacillus subtilis        levansucrase gene), Pen et al., Bio/Technology 10:292 (1992)        (production of transgenic plants that express Bacillus        lichenifonnis α-amylase), Elliot et al., Plant Molec.

Chem. 268:22480 (1993) (site-directed        mutagenesis of barley α-amylase gene), and Fisher et al., Plant        Physiol. 102:1045 (1993) (maize endosperm starch branching        enzyme II).

Methods for Soybean Transformation—Numerous methods for planttransformation have been developed, including biological and physical,plant transformation protocols. See, for example, Miki et al.,“Procedures for Introducing Foreign DNA into Plants” in Methods in PlantMolecular Biology and Biotechnology, Glick B. R. and Thompson, J. E.Eds. (CRC Press, Inc., Boca Raton, 1993) pages 67-88. In addition,expression vectors and in vitro culture methods for plant cell or tissuetransformation and regeneration of plants are available. See, forexample, Gruber et al., “Vectors for Plant Transformation” in Methods inPlant Molecular Biology and Biotechnology, Glick B. R. and Thompson, J.E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages 89-119.

-   -   A. Agrobacterium-mediated Transformation—One method for        introducing an expression vector into plants is based on the        natural transformation system of Agrobacterium. See, for        example, Horsch et al., Science 227:1229(1985). A. tumefaciens        and A. rhizogenes are plant pathogenic soil bacteria which        geneticallytransform plant cells. The Ti and Ri plasmids of A.        tumefaciens and A. rhizogenes, respectively, carry genes        responsible for genetic transformation of the plant. See, for        example, Kado, C. I., Crit. Rev. Plant Sci. 10:1 (1991).        Descriptions of Agrobacterium vector systems and methods for        Agrobacterium-mediated gene transfer are provided by Gruber et        al., supra, Miki et al., supra, and Moloney et al., Plant Cell        Reports 8:238 (1989). See also, U.S. Pat. No. 5,563,055        (Townsend and Thomas), issued Oct. 8, 1996.    -   B. Direct Gene Transfer—Several methods of plant transformation,        collectively referred to as direct gene transfer, have been        developed as an alternative to Agrobacterium-mediated        transformation. A generally applicable method of plant        transformation is microprojectile-mediated transformation        wherein DNA is carried on the surface of microprojectiles        measuring 1 to 4 μm. The expression vector is introduced into        plant tissues with a biolistic device that accelerates the        microprojectiles to speeds of 300 to 600 m/s which is sufficient        to penetrate plant cell walls and membranes. Sanford et al.,        Part. Sci. Technol. 5:27 (1987), Sanford, J. C., Trends Biotech.        6:299 (1988), Klein et al., Bio/Technology 6:559-563 (1988),        Sanford, J. C., Physiol Plant 7:206 (1990), Klein et al.,        Biotechnology 10:268 (1992). See also U.S. Pat. No. 5,015,580        (Christou, et al.), issued May 14, 1991; U.S. Pat. No. 5,322,783        (Tomes, et al), issued Jun. 21, 1994.

Another method for physical delivery of DNA to plants is sonication oftarget cells. Zhang et al., Bio/Technology 9:996 (1991). Alternatively,liposome or spheroplast fusion have been used to introduce expressionvectors into plants. Deshayes et al., EMBO J., 4:2731 (1985), Christouet al., Proc Natl. Acad. Sci. U.S.A. 84:3962 (1987). Direct uptake ofDNA into protoplasts using CaCl₂ precipitation, polyvinyl alcohol orpoly-L-omithine have also been reported. Hain et al., Mol. Gen. Genet.199:161 (1985) and Draper et al., Plant Cell Physiol. 23:451 (1982).Electroporation of protoplasts and whole cells and tissues have alsobeen described. Donn et al., In Abstracts of VIIth InternationalCongress on Plant Cell and Tissue Culture |APTC, A2-38, p 53 (1990);D'Halluin et al., Plant Cell 4:1495-1505 (1992) and Spencer et al.,Plant Mol. Biol. 24:51-61 (1994).

Following transformation of soybean target tissues, expression of theabove-described selectable marker genes allows for preferentialselection of transformed cells, tissues and/or plants, usingregeneration and selection methods now well known in the art.

The foregoing methods for transformation would typically be used forproducing a transgenic variety. The transgenic variety could then becrossed, with another (non-transformed or transformed) variety, in orderto produce a new transgenic variety. Alternatively, a genetic traitwhich has been engineered into a particular soybean line using theforegoing transformation techniques could be moved into another lineusing traditional backcrossing techniques that are well known in theplant breeding arts. For example, a backcrossing approach could be usedto move an engineered trait from a public, non-elite variety into anelite variety, or from a variety containing a foreign gene in its genomeinto a variety or varieties which do not contain that gene. As usedherein, “crossing” can refer to a simple X by Y cross, or the process ofbackcrossing, depending on the context.

Tissue Culture of Soybeans—When the term soybean plant is used in thecontext of the present invention, this also includes any single geneconversions of that variety. The term single gene converted plant asused herein refers to those soybean plants which are developed by aplant breeding technique called backcrossing wherein essentially all ofthe desired morphological and physiological characteristics of a varietyare recovered in addition to the single gene transferred into thevariety via the backcrossing technique. Backcrossing methods can be usedwith the present invention to improve or introduce a characteristic intothe variety. The term backcrossing as used herein refers to the repeatedcrossing of a hybrid progeny back to the recurrent parent. The parentalsoybean plant which contributes the gene for the desired characteristicis termed the nonrecurrent or donor parent. This terminology refers tothe fact that the nonrecurrent parent is used one time in the backcrossprotocol and therefore does not recur. The parental soybean plant towhich the gene or genes from the nonrecurrent parent are transferred isknown as the recurrent parent as it is used for several rounds in thebackcrossing protocol (Poehlman & Sleper, 1994; Fehr, 1987). In atypical backcross protocol, the original variety of interest (recurrentparent) is crossed to a second variety (nonrecurrent parent) thatcarries the single gene of interest to be transferred. The resultingprogeny from this cross are then crossed again to the recurrent parentand the process is repeated until a soybean plant is obtained whereinessentially all of the desired morphological and physiologicalcharacteristics of the recurrent parent are recovered in the convertedplant, in addition to the single transferred gene from the nonrecurrentparent.

The selection of a suitable recurrent parent is an important step for asuccessful backcrossing procedure. The goal of a backcross protocol isto alter or substitute a single trait or characteristic in the originalvariety. To accomplish this, a single gene of the recurrent variety ismodified or substituted with the desired gene from the nonrecurrentparent, while retaining essentially all of the rest of the desiredgenetic, and therefore the desired physiological and morphological,constitution of the original variety. The choice of the particularnonrecurrent parent will depend on the purpose of the backcross, one ofthe major purposes is to add some commercially desirable, agronomicallyimportant trait to the plant. The exact backcrossing protocol willdepend on the characteristic or trait being altered to determine anappropriate testing protocol. Although backcrossing methods aresimplified when the characteristic being transferred is a dominantallele, a recessive allele may also be transferred. In this instance itmay be necessary to introduce a test of the progeny to determine if thedesired characteristic has been successfully transferred.

Many single gene traits have been identified that are not regularlyselected for in the development of a new variety but that can beimproved by backcrossing techniques. Single gene traits may or may notbe transgenic, examples of these traits include but are not limited to,male sterility, waxy starch, herbicide resistance, resistance forbacterial, fungal, or viral disease, insect resistance, male fertility,enhanced nutritional quality, industrial usage, yield stability andyield enhancement. These genes are generally inherited through thenucleus. Several of these single gene traits are described in U.S. Pat.Nos. 5,959,185, 5,973,234 and 5,977,445, the disclosures of which arespecifically hereby incorporated by reference.

Further reproduction of the variety can occur by tissue culture andregeneration. Tissue culture of various tissues of soybeans andregeneration of plants therefrom is well know and widely published. Forexample, reference may be had to Komatsuda, T. et al., “Genotype XSucrose Interactions for Somatic Embryogenesis in Soybean,” Crop Sci.31:333-337 (1991); Stephens, P. A., et al., “Agronomic Evaluation ofTissue-Culture-Derived Soybean Plants,” Theor. Appl. Genet. (1991)82:633-635; Komatsuda, T. et al., “Maturation and Germination of SomaticEmbryos as Affected by Sucrose and Plant Growth Regulators in SoybeansGlycine gracilis Skvortz and Glycine max (L.) Merr.” Plant Cell, Tissueand Organ Culture, 28:103-113 (1992); Dhir, S. et al., “Regeneration ofFertile Plants from Protoplasts of Soybean (Glycine max L. Merr.);Genotypic Differences in Culture Response,” Plant Cell Reports (1992)11:285-289; Pandey, P. et al., “Plant Regeneration from Leaf andHypocotyl Explants of Glycine-wightii (W. and A.)

No. 5,008,200 issued Apr. 16, 1991 to Ranch et al., the disclosuresof which are hereby incorporated herein in their entirety by reference.Thus, another aspect of this invention is to provide cells which upongrowth and differentiation produce soybean plants having thephysiological and morphological characteristics of soybean varietySG1330NRR.

As used herein, the term “tissue culture” indicates a compositioncomprising isolated cells of the same or a different type or acollection of such cells organized into parts of a plant. Exemplarytypes of tissue cultures are protoplasts, calli, plant clumps, and plantcells that can generate tissue culture that are intact in plants orparts of plants, such as embryos, pollen, flowers, seeds, pods, leaves,stems, roots, root tips, anthers, and the like. Means for preparing andmaintaining plant tissue culture are well known in the art. By way ofexample, a tissue culture comprising organs has been used to produceregenerated plants. U.S. Pat. Nos. 5,959,185; 5,973,234 and 5,977,445,described certain techniques, the disclosures of which are incorporatedherein by reference.

This invention also is directed to methods for producing a soybean plantby crossing a first parent soybean plant with a second parent soybeanplant wherein the first or second parent soybean plant is a soybeanplant of the variety SG1330NRR. Further, both first and second parentsoybean plants can come from the soybean variety SG1330NRR. Thus, anysuch methods using the soybean variety SG1330NRR are part of thisinvention: selfing, backcrosses, hybrid production, crosses topopulations, and the like. All plants produced using soybean varietySG1330NRR as a parent are within the scope of this invention, includingthose developed from varieties derived from soybean variety SG1330NRR.Advantageously, the soybean variety could be used in crosses with other,different, soybean plants to produce first generation (F₁) soybeanhybrid seeds and plants with superior characteristics. The variety ofthe invention can also be used for transformation where exogenous genesare introduced and expressed by the variety of the invention. Geneticvariants created either through traditional breeding methods usingvariety SG1330NRR or through transformation of SG1330NRR by any of anumber of protocols known to those of skill in the art are intended tobe within the scope of this invention. [0137] As used herein, the termplant includes plant cells, plant protoplasts, plant cell tissuecultures from which soybean plants can be regenerated, plant calli,plant clumps, and plant cells that are intact in plants or parts ofplants, such as embryos, pollen, ovules, flowers, pods, leaves, roots,root tips, anthers, and the like.

Industrial Uses

The seed of soybean variety SG1330NRR, the plant produced from the seed,the hybrid soybean plant produced from the crossing of the variety withany other soybean plant, hybrid seed, and various parts of the hybridsoybean plant can be utilized for human food, livestock feed, and as araw material in industry.

The soybean is the world's leading source of vegetable oil and proteinmeal. The oil extracted from soybeans is used for cooking oil,margarine, and salad dressings. Soybean oil is composed of saturated,monounsaturated and polyunsaturated fatty acids. It has a typicalcomposition of 11% palmitic, 4% stearic, 25% oleic, 50% linoleic and 9%linolenic fatty acid content (“Economic Implications of Modified SoybeanTraits Summary Report”, Iowa Soybean Promotion Board and AmericanSoybean Association Special Report 92S, May 1990). Changes in fatty acidcomposition for improved oxidative stability and nutrition areconstantly sought after. Industrial uses of soybean oil which issubjected to further processing include ingredients for paints,plastics, fibers, detergents, cosmetics and lubricants. Soybean oil maybe split, inter-esterified, sulfurized, epoxidized, polymerized,ethoxylated, or cleaved. Designing and producing soybean oil derivativeswith improved functionality, oliochemistry, is a rapidly growing field.The typical mixture of triglycerides is usually split and separated intopure fatty acids, which are then combined with petroleum-derivedalcohols or acids, nitrogen, sulfonates, chlorine, or with fattyalcohols derived from fats and oils.

Soybean is also used as a food source for both animals and humans.Soybean is widely used as a source of protein for animal feeds forpoultry, swine and cattle. During processing of whole soybeans, thefibrous hull is removed and the oil is extracted. The remaining soybeanmeal is a combination of carbohydrates and approximately 50% protein.

For human consumption soybean meal is made into soybean flour which isprocessed to protein concentrates used for meat extenders or specialtypet foods. Production of edible protein ingredients from soybean offersa healthy, less expensive replacement for animal protein in meats aswell as dairy-type products.
